What is Prediction of Motions of an Airplane Resulting from Abrupt Movement of Lateral or Directional Controls about?

A procedure is presented for determining the motions of an airplane resulting from the deflection of the lateral or directional controls for the case of non-linear derivatives. The step-by-step integration on which the procedure is based considers the rolling, the yawing, and the lateral accelerations computed from wind-tunnel data as functions of the sideslip angle. A sample computation table is presented to illustrate the application of the procedure. A comparison is made of different methods for calculating the disturbed motions of an airplane resulting from an abrupt aileron movement. Experimental data, which were obtained from conventional wind-tunnel tests of a model of a recent fighter airplane, are used in the computations for comparing the various methods. The resulting solutions show that, for the case of nonlinear derivatives, the calculated motions are in better agreement with the results obtained from flight tests if the rolling and yawing accelerations computed from static-model tests are condisered as functions of the sideslip angle. The lateral acceleration, which is often assumed to be negligible, should be considered. The variation of the rolling and yawing accele
